A method for indicating relative position information of a common control resource set (CORESET) of remaining minimum system information (RMSI) includes: determining indication information included in a physical broadcast channel (PBCH) of a synchronization signal block (SSB), the indication information including first indication information indicating a relative position between a CORESET of RMSI corresponding to the SSB and the SSB; and sending the SSB including the indication information and the CORESET of the RMSI to user equipment (UE).
